- Yahoo Sideline is an app that lets you keep track of Twitter searches you make often, updates them in real-time, and lets you skim them in tandem. Think TweetDeck for the buzz-thirsty. (More thoughts at Mashable.)

A week or so ago we told you about this thing called RoadTwip. Surely, you thought we meant Road Trip, right. After all, there's typos on Adrants all the time. But no, We got it right this time. It really is RoadTwip.

So what the hell is RoadTwip. Well, it *is* a road trip but it's so much more as well. The goal of RoadTwip, as one third of the RoadTwip crew, Jolie O'Dell, writes on ReadWriteWeb, is to "stop spinning on the NYC/SF/LA axis of the tech world, get outside the echo chamber, test the IRL capabilities of social media, and get a glimpse of something new and authentic."

Half of Adrants is Asian, which means we were irreparably traumatized by karaoke from an early age. But there's a contagious warmth to this effort by T-Mobile -- which can only be described as the Ultimate Karaoke Gangbang.

The mobile/communications firm projected the lyrics to the Beatles' Hey Jude over a billboard, then passed mics out to people on Trafalgar Square. It's neat to watch the faces: people look earnest, but uncertain, and over time they just kinda lose themselves in the na-na-nas and the feel-good Hey Jude-in'.

On May 4, Heavy.com will launch the Massive Mating Game, a Twitter-based dating contest. The game, in its third year but its first involving Twitter, will ask people to follow @HEAVYsan. A tweet will announce each time one of the HEAVY girls posts a video a question will be asked about the content of the video.

The first person who answers the question correctly wins a prize and will have a one in forty chance of wining a two night stay in Las Vegas with the girl whose videos are streamed the most.

So yes, over the next eight weeks, horny male ad sluts (well, horny males no matter the industry in which they work) will slather over @HEAVYsan's tweets drooling for the next update. OK, not so much but it is an interesting mental image - of how easily guys can be manipulated.
